Title: Switch mode power supply
Inventor: BARII ENU KIYARORU
IPC: H02M1/34
Filed: 1991-10-08
Abstract: PURPOSE: To suppress electromagnetic interference by providing a snubber capacitor SC connected in parallel with a primary inductance FI, and a snubber inductor SI connected in series between the FI and a transistor switch TS. CONSTITUTION: When a TS 42 is turned on, an SC 156 is charged with a voltage being applied to an FI 32 and detected as a positive voltage at a terminal 30. When the TS 42 is turned off, resistance thereof is increased and the current passing through the FI 32 is decreased thus inverting the voltage polarity of the FS 32. Consequently, the majority of current is directed from the TS 42 toward the SC 156 and voltage rise rate at an input terminal 40 is limited thus suppressing electromagnetic interference. When the TS 42 is turned off thoroughly, the SI 38 absorbs a resonance voltage at the input terminal 40 and thereby conduction radiation is reduced. When the TS 42 is turned on again, the SI 38 enters into high impedance state where the turn on rate of the TS 42 is decreased until saturation thus suppressing electromagnetic interference.

Abstract: PURPOSE:To provide a reforming device capable of preventing oxidation of reforming catalyst due to leakage of external air during suspension of operation without using inert gas for purging by providing a bypass pipe short-circuiting a reforming furnace and a feed tank between the furnace and the tank interposing a valve. CONSTITUTION:In a device for forming reformed gas contg.

When operation is suspended, the temp. of a reforming furnace 1 is dropped and the pressure in the furnace becomes negative by the cooling and condensation of methanol vapor. When the pressure drop between the negative pressure and the atmospheric pressure attains a specified value, the second bypass valve 19 in the bypass pipe 38 is opened. Liquid methanol is sucked in the reforming line and reforming catalyst 8 packed in a catalyst pipe 7 is dipped in the liquid methanol. Therefore, oxidation of the reforming catalyst is prevented even if external air is introduced through valves or seals due to insufficient air tightness against the negative pressure.
